On-site for a depo shot and not sure if I should. I"'ll be 50 in August..I"'ve been having constant headaches, hair loss, feeling bigger, weight gain about 15 lbs but I can't get it off. I have previously lost 96lbs and have kept it off 7 yrs. No sex drive, and always tired. Problem is I smoke and have few options for birth control. I also have no insurance so I"m not able to have a lot of tests done. Your suggestion please....AAAA
